Are Dolphins Really That Smart and Does It Make Us Like Them More When They Are? (2019-2020)
Studies suggest that anthropomorphic framing of animal cognition can lead to positive changes in human attitudes toward conservation. However, no research has been done on a species, such as dolphins, that does not have a human-like appearance (as opposed to most primates).
This Bass Connections project will study how dolphins use energy to solve cognitive problems and how the perception of dolphin intelligence by the public shapes attitudes toward their conservation. This research will represent the first experimental study assessing how beliefs about animal minds shape our psychology regarding conservation.
This project team will design and implement two related experiments that will be conducted during Spring Break 2020. Team leaders will host a joint weekly seminar through the 2019-2020 school year to focus on the planning of these two projects.
The first study will focus on comparing the total energy expenditure of several dolphins while they participate in a series of cognitive tasks and during a control period. This cognitive energetics project will take advantage of Dr. Herman Pontzer’s expertise using doubly labeled water to asses total energy expenditure. The doubly labeled water method is a noninvasive technique that is considered to be the gold-standard method for measuring daily calorific needs. Since no previous research has examined dolphin total energy expenditure, this project will provide the first cognitive energetics data ever collected on dolphins.
The second study will include an experimental survey of visitors to a research center for dolphins to evaluate whether the perception of human-like cognitive skills in dolphins influences visitor attitudes and conservation-related behaviors. The project team will conduct an experimental survey in which half the visitors to the center are told that our research findings suggest dolphins have human-like cognition while the other half will be told we are finding that dolphin cognition is not human-like. Researchers will then assess how this framing alters visitor attitudes and their tendency to donate to the center and dolphin conservation.
Two manuscripts for publication; student-led seminars and poster presentations for research dissemination; grant proposals for larger external funding based on pilot project results
Fall 2019 – Spring 2020
- Fall 2019: Begin weekly joint seminars to discuss papers on animal cognition, brain evolution, energetics and conservation psychology relevant to proposed cetacean research
- Spring 2020: Continue weekly seminars to design cognitive energetics and conservation psychology research projects; take Spring Break trip to conduct cognitive energetics and conservation psychology experiments; continue weekly seminars to discuss results; begin developing conservation psychology manuscript for publication; discuss next steps for cognitive/energetics research; plan proposals for further funding based on pilot project results; prepare student-led seminars or poster presentations for research dissemination
